SUPZEOR'I'ING FRAME FOR BEDSPRINGS.

Application filed August 8, 1923. Serial No, 656,413.

To all whom it may concern Be it known that we, ROBERT B. HARRI- son and JosnrI-I SILVESTER, citizens of the United States, and residents of Ingram and Pittsburgh, respectively, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Supporting Frames for Bedsprings, of which the following is a specification.

This invention relates to supporting frames, and particularly to a bed spring supporting frame which may be used either p in connection with wooden bedsteads or hung from the side rails of metal beds.

It is an object of the invention to provide a device of this character which is simple in construction, economical to manufacture, easily adjusted to accommodate the same to either wooden or metal beds, and which is highly efficient in operation.

It is a special object to provide a bed spring supporting frame equipped with supporting devices which are of sturdy construction, which can be readily swung into or out of operative relation and which are connected to and pivotally mounted upon the frame in such manner as to positively preclude pivotal movement between the parts except in a planetransverse to the frame.

It is a special object to provide a frame having supporting devices comprising stirrups and hangers rigidly connected together so as to preclude pivotal movement therebetween and forming a unit which may be readily applied to the frame during the initial construction thereof or for purposes of replacement.

It is still a further special object to pivotally susp'endthe said units comprising'the stirrups and hangers from. theframe without the use of bolts or "rivets in 'such'mann'er as to enable the saidunits to be readily attached to or, detached from the slats of the frame.

These and other objects of the invention will more fully appear when taken in conjunction with' the following description and the appended claim.

in the accompanying drawings, Fig. '1 "is plan view of two-section bed spring equipped with the preferred embodiment of theinvention; Fig. 2 a side elevation of the sprmg shown in Fig. 1 illustrating the same in closed position, that is, with the sections in superposed relation, Fig. 3 a plan view of the bottom frame detached from the remaining parts of the spring for the purpose of clearness; Fig. '4: an enlarged perspective View illustrating the details of construction of one type of supporting device; Fig. 5 a similar view of another form of supporting device; Fig. 6 a like view of a still further modified form of supporting device; and Fig. 7 an enlarged detail view, partly in section and partly in elevation, showing the method of suspending the frame upon the side rails of a metal bed.

Preferably the spring with which the invention is employed is constructed in two sections, a and 6, each section comprising a metallic rectangular frame 1 connected by the hinges 2. The sections a and b when in open position, as illustrated in Fig. 1, are adaptedto-fit upon either a'metal or a wooden bedstead, and when closed, as illustrated in Fig. 2, forming a compact structure ca pable of being easily handled. The two sections are identical in construction and are hinged as described merely for convenience in handling, it being understood that if desired the frame may be made in but a single section corresponding to the size of the bed with which it is to be used.

In connection with the rectangular frame which forms the top of the bed spring a rectangular frame 3 forming the bottom of the spring is used. The frame 3 is somewhat smaller than the frame 1 and comprises the side rails 4, 4, and the

end rails

5, 5, conveniently secured in any desirable manner. Extending between the side rails 4,4, and suitably connected thereto as by riveting at 6 are a plurality of spaced transverse slats 7. The topframe .1. and the bottom frame 3-are connected together by a plurality of conical shaped springs 8, the

ends of thesprings being secured at one end tio-the slats and rails of the bottom frame while their opposite .endsare supported by interweaving with the wires 9 carried by the frame .1, as illustrated in Fig. 1. The

manner of connecting the springs and interweaving the springs and wires form no part of the present invention and are illustrated and described merely for the purpose of more fully setting forth the invention forming the subject matter of the present application.

Between each end rail 5 and the contiguous slats 7 and also located at suitable intervals between contiguous slats 7, and at each side of the bottom frame 3, are supporting devices comprising the stirrup or strap 10 and the hanger 11. The stirrup 10 is U-shaped, being provided with the laterally projecting apertured

ears

12, 12 at its opposite ends, while its intermediate portion substantially midway between its cars is offset so as to form a depressed re cess preferably corresponding in width and depth to that of the inner end of the body of the hanger 11. The depression formed by this offset portion receives the inner end of the hanger 11, the two being firmly united by riveting or welding as indicated at 13. The stirrup and hanger are thus rig idly connectedtogether, and due to the neat fit of the inner end of the hanger within the offset depressed portion of the stirrup all pivotal movement therebetween is positively prevented. The outer extremity of the hanger is equipped with the hooked portion 1% which is adapted to engage the side rail 15 when the frame is used in connection with metal beds, as clearly shown in Fig. 7

Preferably, the stirrup and hanger are operatively associated. with a rod forming a unit therewith, and functioning as a pivotal support suspending the said parts from the slats 7 This rod is indicated in the embodiment shown in Fig. t by the reference numeral 16. The main body of the rod is circular in cross section and projects through correspondingly shaped apertures in the

terminal ears

12, 12. The

extremities

17, 17 of the red at a point beyond the ears, are somewhat enlarged and elongated so as to prevent the rod from being disconnected from the stirrup, and for a purpose to be subsequently described the enlargements are disposed at substantially right angles to each other. The stirrup,the hanger, and the rod are thus locked together and comprise a unit facilitating the handling of the supporting devices. The enlarged extremities, besides functioning to lock the rod to the stirrup also serve to detachably connect the supporting unit to the frame. For this purpose contiguous slats are provided with aligned

elongated apertures

18, 18 of sufficient size to permit passage of the

enlargements

17, 17 when the rod is turned to cause the enlargements to register with the apertures in the slats. However, after the enlargement has been passed through its aperture, subsequent turning movement of the rod will bring the parts into such relation as to prevent sul sequent withdrawal thereof until the enlargement has been again turned so as to be brought into register. Due to the fact that both of the

apertures

18, 18 extend in the same general direction. and the enlargements 1?, 17 are disposed at an angle to each other, it is obvious that but one of the enlargements can be made to register with its aperture at the same time, thus preventing accidental detachment of the supporting unit. The exact angular relation, just described, is merely ilhistrative of one relation which the parts may assume, it being noted that any relative angular relation between the enlargements and the apertures in the slats which will prevent the passage of the enlargements at both ends of the rod simultaneously is within the contemplated scope of the invention.

Another form of detachable supporting unit is shown in Fig 5. The pivot rod which is designated at 19 is circular in cross section throughout substantially its entire extent and projects through correspondingly shaped apertures in the

ears

12, 12. In this form the rod is connected to the stirrups by increasing its cross sectional dimension, as by flattening at the

points

20,20 immediately adjacent the said ears. The c):- tremities of the rod beyond the ears are circular and are adapted to be projected through correspondingly shaped apertures provided in the slats as clearly shown in the drawings. In this embodiment the supporting unit is assembled by simply passing the extremities of the rod 19 through the apertures in the slats, prior to the riveting of the slats in position, or by forcibly springing the slats apart sutiicient to permit the extremities of the pivot rod to be passed through the apertures after which the slats are released so as to resume their normal po sition as shown in the drawings.

It is obvious from the above description that both of the forms illustrated in detail in Figs. 4: and 5 may be readily engaged with the slats of the frame either during initial construction or may be attached or detached, if desirable, as in cases requiring replacement of broken supporting units, by forcibly springing the slats 7 apart sufficiently to engage the extremities of the pivot rods with the apertures in the slats.

The form shown in Fig. 6 while embodying the novel feature of rigidly connecting the stirrup and hanger does not include the unitary and detachable features of the previously described forms. In the embodiment of Fig. 6 the pivot rod 21 is merely passed through the apertures in the

ears

12, 12 as well as in the slats and the extremities of the rod beyond the slats flattened so as to increase its cross sectional area for the purpose of locking the parts in operative position as clearly shown in the drawings.

The position which the hanger assumes when the frame is used in connection with metal beds is shown in full lines in Fig. 7, and the frame is suspend-ed by engaging the hookeds ends 14 of the hangers with the side rails 15, as previously indicated. By adjusting the hangers to the position shown by the dotted lines in said figure so that they extend inwardly between the slats 7, the spring may be used with wooden beds, the slats serving to support the spring by resting upon the usual wooden slats customarily used in connection with a wooden bed. The hangers may be readily adjust-ed from the one position to the other by simply swinging the same upon their pivotal connections and the frictional contact between the sev eral parts is sufficient to maintain the hangers in adjusted position.

It is thus seen that the invention provides a simple means for suspending the frame from the side rails of metal beds and permits adjustments rendering it capable of being used in connection with wooden beds, one which is sturdy in construction, and economical tov manufacture, one which can be readily adjusted, one in which swinging movement of the supporting device is positively confined to a plane transverse to the frame, one in which the st-irrups and hangers are locked against relative pivotal movement, and one in which the supporting devices form a separate unit which can be readily attached or detached from the frame in the manner described without the use of bolts, rivets, or similar attaching means.

Weclaim:

A bed spring supporting frame comprising a plurality of spaced transverse slats, contiguous slats being provided with elongated apertures disposed in alignment with each other, a supporting device pivotally suspended from and interposed between contiguous slats including a U-shaped stirrup having apertures in its terminal cars, a pivot rod extending through apertures in said ears and provided with elongated enlargements at its extremities beyond the said ears whereby to lock the rod to the stirrup, said enlargements being of such dimension as to permit passage of the same through the elongated apertures in the slats when the rod is moved to a predetermined angular relation with respect to the said apertures, the angular disposition of the elongated apertures and the enlargements being such that both enlargements cannot pass through the coopcrating apertures simultaneously, the intermediate portion of the stirrup being offset to, form a depression, and the inner end of the hanger being connected to the stirrup and neatly fitting within the said depression whereby to prevent pivotal movement between the stirrup and hanger.

In testimony whereof, we hereunto sign vur names.
